Electronic Device

1. An electronic device comprising: a main body; a display disposed on the main body for displaying information; a plate member having a transparent central section overlying the display and a colored section adjacent the transparent central section and positioned other than overlying the display; and a driving unit connected to the colored section of the plate member for vibrating the plate member to cause the plate member to create a sound in response to an audio signal, the driving unit comprising: a planar voice coil; a resilient member; a support section moveably attached to the colored section of the plate member by said resilient member; and a first magnet disposed inside the planar voice coil and a second magnet disposed outside the planar voice coil, wherein the first and second magnets are fixedly attached to the support section.

2. The electronic device as claimed in claim 1 , wherein the first and second magnets are installed on the colored, section of the plate member.

3. The electronic device as claimed in claim 2 , wherein the planar voice coil comprises a shape of a quadrilateral frame and the first and second magnets are quadrilateral shaped complementary to the shape of the planar voice coil.

4. The electronic device as claimed in claim 2 , further comprising a second planar voice coil adjacent the first voice coil in a direction orthogonal to a surface on which the first voice coil is installed.

5. The electronic device as claimed in claim 1 , wherein the planar voice coil is installed on the colored section of the plate member.

6. The electronic device as claimed in claim 5 , wherein the planar voice coil comprises a shape of a quadrilateral frame and the first and second magnets are quadrilateral shaped complementary to the shape of the planar voice coil.

7. The electronic device as claimed in claim 5 , further comprising a second planar voice coil adjacent the first voice coil in the direction orthogonal to a surface of the colored section on which the first voice coil is installed.

8. The electronic device as claimed in claim 1 , further comprising a plurality of driving units installed at plural places on the colored section of the plate member.

9. The electronic device as claimed in claim 1 , wherein the colored section comprises an edge section circumscribing the transparent central section.

10. The electronic device as claimed in claim 1 , wherein the planar voice coil is fixedly attached to the colored section of the plate member.
